Transducer clamping device

Abstract

A clamping device for removably attaching a transducer of the probe type to a gage comprises a block having a first end attached to the body of the gage and a second end spaced slightly therefrom, with a tunnel between the two ends aligned with a matching tunnel through the gage body. The gage body tunnel closely surrounds the tubular stem of the gage, while the block tunnel is slightly radially spaced therefrom. A clamping bolt draws the second end down into engagement with the gage body, which creates an axial misalignment of the tunnels to bring the block tunnel wall into clamping engagement with the probe, the misalignment and clamping force controlled by the spacing of the second end.

The embodiments of the invention in which an exclusive property of privilege is claimed are defined as follows: 
     
       1. A clamping device adapted for use with a flow-through gage or the like to releasably mount and fixedly position a transducer probe having a tubular stem relative to the body of said flow-through gage or the like, comprising: a block member having a first end rigidly attached to a surface of the gage body and a second end normally spaced from the surface of the gage body by a predetermined amount,   the block member further including a tunnel therethrough between the first and second ends normally axially aligned with a tunnel through the gage body, the wall of the gage body tunnel closely confining the tubular stem of the transducer probe, and the wall of the block tunnel being normally radially spaced from the tubular stem by a predetermined amount,   the block member also including a weakened portion between the block tunnel and the rigidly attached first end, and   tightening means in one mode engaging the second end with the gage body surface from which it is normally spaced by deforming the block member about the weakened portion causing a controlled axial misalignment of the block member tunnel relative to the tubular stem sufficient to bring the wall of the block member tunnel into clamping engagement therewith to fixedly position the probe relative to the gage body with the pressure holding said probe being absolutely controlled and predetermined by the engagement of the normally spaced second end with the gage body surface, the tightening means in another mode restoring the normal spacing of the second end from the gage body surface and the normal axial alignment of the tunnels to release the probe from the gage body.
